VENT CONNECTION FOR AWNING TYPE wINDows Filed Jan. 20, 1960 3 Sheets-Sheet 3 INVENTOR. Morton Tucker Attorney United States Patent O Filed Ian. 20, 1960, Ser. No. 3,559 3 Claims. (Cl. 189-67) This invention relates to an improvement in window devices of the type commonly known as awning windows and wherein a plurality of sash devices are pivotally supported in a horizontal plane to swing in a vertical manner to and from an overlapping relation with respect to each other and an overlapping relation with respect to a main frame.

Window devices of the awning type are commonly assembled with respect to hinge elements and actuating linkage and it is customary to install the vent frames into the main frame and permanently secure it to the hinge elements prior to installation of the main frame and the mounted vent frames into a wall opem'ng after which, the vent frames are suitably glazed.

The prime object of this invention is to provide novel means whereby the vent frames may be supplied separately from the assembled main frame and the linkage, to be subsequently inserted and anchored with respect to the hinge elements, thus permitting the vent frames to be glazed at the factory for transportation to and assembled with respect to the installed frames and with the vent frames being installed with respect to the main frames and the operating linkage in a simple manner that also facilitates the removal of any individual vent frame, should the occasion require.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the acpanying drawings wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

FIGURE 5 is a vertical section to the main frame, taken substantially on line 55 of FIGURE 7,

FIGURE 6 is a view similar to FIGURE 5 but illustrating the vent frame shifted to the open position, and

FIGURE 7 is a horizontal section taken substantially on line 7-7 of FIGURE 5.

Referring specificallyto the drawings, wherein is shown a preferred embodiment of the invention, the numeral 10 designates generally a main rectangular frame of the type commonly formed from extruded aluminum members and being of a size to accommodate any preferred I number of vertically swingable window sashes 11.

The main frame 10 embodies vertical frame sides 12 which are generally channel-shaped in cross section to form outer vertical webs 13, rear walls 14, and inner vertical webs 15. The webs 12 are channeled to receive vertically shiftable operator bars 16. The bars 2,990,039 Patented June .27, 1961v ice 16 are vertically shiftable by conventional winding mechanism and linkage, not shown.

P-ivotally connected by shoulder rivets 17, see particularly FIGURE 3, are hinge plates, indicated as a whole by the numeral 18. The several hinge plates 18 are arranged at opposite sides of the main frame and constitute the mounting means for the vent frames 11.- The hinge plates 18 embody a flat elongated plate section 19, an outwardly angled intermediate section 20 and a rearwardly curved tongue 21. The tongue 21 is apertured at 22 to receive the studs or rivets 17 and whereby the hinge plates may freely swing in a vertical plane with respect to the operator bars 16. The angle plate section 20 is apertured at 22', to receive fastening screws 23, for a purpose to be presently described. Adjacent the lower end of the plate section 19, there is provided an aperture 24 that receives the shank portion 25 of a pivot stud 26. The pivot stud 26 is pivotally connected to a fulcrum bar 27 and the fulcrum bar is pivotally connected at 28 to the web portion 15 of the main frame, such being conventional construction in awning type windows. It will be apparent, that the hinge elements 18 are formed in right and left handed manner to support the vents 11 upon opposite sides of the main frame and a right and left hand hinge constitutes the mounting for-one vent frame 11 and it will be apparent of course that multiple vents may be supported within the main frame in accordance with its size but in each instance, there is provided a pair of hinge plates 18 for each vent and a pair of fulcrum arms for each vent while the bar 16 is commonly connected to all of the hinge. elements.

Each vent frame 11 embodies extruded aluminum end jambs 29 and upper and lower connecting extruded channeled rails 30. The web portion 31 of the upper rails 30 of each vent is extended outwardly beyond the ends of the jamb members 29 and is angled upwardly at 32 and perforated at 33, for the passage of the screws 23. The angularity of the angled end 32 is substantially identical to the angularity of the plate section 20 of the hinges 18. The jamb members 29 have outwardly facing channels 34 and with the "width of the channel being co-extensive with the width of the plate section 19 of the hinges whereby the plate sections 19 may be engaged within the channels 34 to be held against lateral movement. The web portion 35 of the jamb members 29, downwardly from the upper rails 30, are provided with keyhole slots 36. The stud extension 25 at its free end is provided with a shouldered collar 37, having a diam eter slightly smaller than the largest dimension of the keyhole slot 36. The collar 37 and its hub portion 38 are fixed upon the studs 25 and are adapted to engage through the keyhole slot 36 to be shifted upwardly for locking engagement into the smaller diameter of the keyhole slot 36'.

In the use of the device, the main frame 10, and associated linkage including the bars 16, the hinge plates 18 and the fulcrum bars 27 are all assembled in their respective relationship to have pivotal connection with each other and with the main frame. With the main frame in an installed relation with respect to a wall opening, the several vents are then shifted through the opening of the frame and then moved downwardly to align the studs 25 with the keyhole openings 36. Since there is some degree of flexibility and looseness with respect to the linkage, it becomes possible to first engage one jamb member 29 with its respective stud 25 and then bodily shift the vent sidewisc to engage the opposite stud 25, at which time the vent is bodily shifted downwardly until the angled web portion 32 of the upper rail engages the angled portion 20 of the hinge plates at 3 a which time, the apertures 22' and 33 are in axial alignment after which, the screws 2-3 are threaded into the threaded openings '22, securely anchoring the vent at its opposite ends with respect to its opposite hinge elements 1-8. In this position, thehub portion 38 has been shifted into the smaller diameter of" the keyhole opening 36,

anchoring the hinge plate 19 into the channel 34 against lateral movement. With the screws 23' firmly in position, the vent is rigidly held with respect to the hinge elements 18. Now, when the bars 16 are shifted under the influence of a conventional winding mechanism, the several hinge elements 18 are shifted downwardly, causing the window to fulcrum outwardly by the fulcrum bars 27, shown more clearly in FIGURE 6. When the vents are to be removed for any purpose, the screws 23 at the opposite ends of the webs 31 are removed and the vent bodily lifted upwardly to align the shoulders 37 of the studs 25 with the larger diameter of the keyhole opening 36. Then, by moving the vent endwise, the vents are disengaged from the studs 25 and permits of the window being lifted bodily from the main frame. It has been found that the device functions more readily by partial opening of the vents, since the vents when in the closed position are all in overlapping position and it would not be possible to lift or remove any individual vent. Vent hinges heretofore have been riveted to the vent frames, necessitating the assembly of the vent frames with the main frames prior to the installation.

It will be apparent from the foregoing that a very novel form of mounting means has been provided for vent frames of the type known as awning windows. The structure is simple, is fully as strong as the rivetedv hinges and greatly facilitates the manufacture and installation of the vents separately from the main frame. Also, it makes it possible to glaze the vent frames prior to their installation. The device is cheap to manufacture and greatly facilitates the installation and removal of any particular vent.

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within. the spirit of the invention as shall be determined by the scope of the subjoined claims.
